Flooding:

Due to the runoff from the copious rainfall, numerous creeks, streams and some rivers have flooded. There have been several reports of county roads and some highways underwater. The NWS in Hastings has issued Flood Warnings for much of north central Kansas and a small part of south central Nebraska.  Interestingly enough, though flooding has been widespread and extensive, eventually most of the water will run into three reservoirs in the area. Harlan County Reservoir, Kirwin Reservoir and Waconda Lake will all be the main beneficiaries of this rainfall as the runoff eventually reaches those three destinations.
